Ultra-Thin Hybrid Ion Exchange Interlayer for High Performance Aqueous Zn Metal Batteries. [PDF]

Adv Sci (Weinh)
An ultra‐thin SPEEK/FCD ion‐exchange interlayer modulates the Zn2+ solvation environment (–SO3−), provides ion‐exchange pathways that homoginized the Zn2+ flux, and via F‐rich chemistry forms in situ ZnF2 that suppresses parasitics and stabilizes the interface; its integrity relieves interfacial stress.

Near-Infrared Switch-Driven Macrophage Dynamically Reprogramming for Anti-Infection and Tissue Healing on Polyetheretherketone Implants. [PDF]

Adv Sci (Weinh)
This study develops a Mg‐H‐SPEEK implant with NIR‐switchable immunomodulatory properties. Under NIR, it promotes M1 macrophages for antibacterial action; without NIR, it induces M2 reprogramming to enhance tissue healing. This dual‐function material offers a smart strategy for reducing infection and improving integration in percutaneous implants ...

Effect of Covalent Organic Frameworks Containing Different Groups on Properties of Sulfonated Poly(ether ether ketone) Matrix Proton Exchange Membranes

Nanomaterials, 2022
The rich −SO3H groups enable sulfonated poly (ether ether ketone) (SPEEK) to possess excellent proton conductivities in proton exchange membrane (PEM), but cause excessive water absorption, resulting in the decline of dimensional stability.
